PCS + Step-Up Integrated Cabin
All-in-one: PCS, transformer, water chiller & switchgear. 20%+ smaller footprint. IP65 rated.
Four pieces of equipment, four vendors, four commissioning interfaces — or one cabin. The ES-S Series packages the PCS, medium-voltage transformer, water chiller and HV switchgear into a single pre-wired, factory-tested unit.
What Integration Buys You
20%+ smaller footprint. 40%+ higher power density. IP65 protection against sand and salt spray — proven at the 550MW Kubuqi desert project. And a commissioning schedule measured in days per block instead of weeks, because the interfaces were tested at the factory, not discovered on site.
The Range
ES-5000S (5MW), ES-6900S (6.9MW), ES-7000S (7MW) and the mid-format ES-5000M. Remote sites — where every extra site interface is a schedule risk — are exactly where these cabins earn their keep.
